The ''Additional Filter'' setting allows you to select custom fields and associated values. These are used to filter the existing activities that will be listed within the XML. The custom fields used have to be those with pre-defined options (e.g. [[Custom Field Type: Select One – Combo Box|Combo box]], [[Custom Field Type: Select Many – Check Boxes|Check Boxes]], [[Custom Field Type: Dynamic Data – Dynamic Control Field|Dynamic Control]], Ajax Lookup).

When building your section, you will need to map the fields on the {{l2}}s that will be referenced by the XML section.
